I bought these for my daughter's bday party, for the girls to decorate and take home. We used acrylic permanent paint pens to color them, and then I sprayed them with an Aileens acrylic sealer. So far they have held up perfectly to hand washing! Quality of the cups, lids,and straws was great, and consistent. Great value for 8 cups, and a great party activity, and favor for my daughter's friends.
